If there were a health marker guaranteed to shape your happiness, your health and your children’s wellbeing, wouldn’t you want to optimise it?

According to today’s guest there is: your relationships. And in this episode, the world-renowned couples’ therapist Terry Real reveals the one skill he believes matters more than any other for lasting love – while showing you exactly how to use it.

Nicknamed ‘the turnaround guy’, Terry has spent decades helping couples who’ve tried it all find their way back to connection. His latest bestseller Us: Getting Past You and Me to Build a More Loving Relationship, features a foreword from one-such happy customer, Bruce Springsteen. Terry’s unconventional yet hugely successful approach, Relational Life Therapy (RLT), has trained thousands of therapists worldwide. He believes a good therapist should take sides, and that lasting change often means helping someone come down from grandiosity, not just raising them up from shame.

This is one of those conversations that blends big, new ideas with nuggets of advice you’ll be itching to put into practice. We discuss how expectations of love and romance have changed over the generations – and why so many of us are trying to build modern, intimate partnerships using skills we were never actually taught. And Terry explains why the real measure of a strong relationship isn’t how rarely you argue, but which of your ‘three selves’ you use to do it.

He introduces the idea of the adaptive child, an old survival pattern that hijacks our behaviour the moment we feel threatened, and explains how learning to recognise it can transform the way we handle conflict. We also discuss the patriarchy and the need to move beyond it for humankind – but this is not about blaming men or women, rather showing how both can and must shift to help each other and the world.

So, what is that one skill we need for lasting love? Terry calls it repair, and his bold idea is that it’s not a two-way conversation. When someone we love is hurt or upset with us, our job is not to explain ourselves, but to help them feel heard first. The ability to repair, more than the ability to swerve an argument altogether, is what determines relationship success – and, crucially, he reveals how to do it. It’s a simple reframe, and one that could change how you handle your very next disagreement.

Whether you are single, married, co-parenting, or navigating a difficult patch with someone you care about, this conversation is full of practical strategies you can start using today. I have a feeling you’ll want to share this episode, so everyone you love can do the same.
